What is your giant reluctance to just fix your axle seals and keep your brakes functioning as intended. Rear axle seals are really NBD at all. Remove the diff cover. You need to change fluid anyway. Remove the cross pin retainer bolt,and cross pin. Push in on the axle pull the c clip Remove the axle. Several methods of removing the seal which is no big deal. Drive in the new seal,push in the axle,replace c clips,cross pin and retainer bolt. Reseal and refill the pumpkin. This is beginner stuff. And way better than rigging brakes on a lifted truck with stiff springs. Yes weight transfer comes into play too. Just remember to heat the cross pin bolt with propane before trying to loosen it. And to any of you that said you need to drain the mastercyinder if you block the rear line at the master. BS. no you don't. You may trip the combination valve though,which you would anyway with no hydraulic pressure from draining the master.
